Hi can someone plss help with this question!!!

Answers

Answer:

Function A < Function B

Step-by-step explanation:

Solving for Function A:

Taking two points: (0,1) and (4,2)

y = mx+c

Substituting (0,1):

1 = 0 + c

c = 1

Substituting (4,2):

2 = 4m+c

Substituting 'c':

2 = 4m + 1

4m = 1

m = 0.25

Comparing slopes (slopes of each - 0.25 and 0.75):

0.75 > 0.25

Hence,

Function A < Function B

What is the quadratic function for this graph?

Answers

Answer:

f(x) = (x + 3)² + 2

Step-by-step explanation:

Vertex for of a quadratic function is given by,

f(x) = a(x - h)² + k

Here, (h, k) is the vertex of the parabola.

From the given picture,

(-3, 2) is the vertex of the graph.

Therefore, function will be,

f(x) = a(x + 3)²+ 2

Since, the graph of the function passes through (0, 11),

f(0) = a(0 + 3)²+ 2

11 = 9a + 2

9a = 9

a = 1

Equation of the function,

f(x) = (x + 3)² + 2
